The alteration of limestone forms crushed marble, metamorphic rocks, by heat and pressure. In its pure form, marble is a white stone with a
crystalline and sugary appearance, consisting of calcium carbonate CaCO3. Usually, marble contains other minerals, including quartz, graphite, pyrite, and iron oxides. Their chemical properties are useful in pharmaceuticals and agriculture. Its optical properties are also useful in cosmetics, paint, and paper. They are used as Industrial Raw Materials with other industrial raw material products such as Silica Flour, Limestone, Aggregate, Quicklime, Talc, Volcanic Rock, and Abrasives.
Properties
Marble is usually a light-colored rock. It is one of the most effective acid neutralization materials. Marble has a hardness of three on the Mohs hardness scale and composes of calcite. As a result, marble is easy to carve, and that makes it useful for producing sculptures and ornamental objects. We polish marble to a high luster after sanding it with progressively finer abrasives. We can use this to cut beautiful pieces of marble. After cutting them, we polish them then use them as floor tiles, architectural panels, facing stone, window sills, stair treads, columns, and many other pieces of decorative stone.
Marble chips work best when used in paths and patios as a substitute for gravel. Although gravel often is used as inorganic mulch around plants, marble chip mulch’s reflected sunlight can be too intense for plants in full-sun locations. Today, marble is quarried all around the world and is used to create giant monuments, it is used in building, even down to applications as simple as kitchen countertops. It’s classified as a metamorphic stone, which means that it has changed composition over time from one type of rock to another.
Crushed Marble also used in:
- Building Stone
- Countertops and sinks
- Floor tiles
- Terrazzo – marble chips mixed with concrete to form floors.
- Tomb Stone
